Answer:
m would be 69!
Step-by-step explanation:
61 = m - 8
61 + 8 = m - 8 + 8
69 = m
-2x + 7y = 10 ⇒ -2x + 7y = 10
x - 3y = -3 ⇒ <u>-2x + 6y = 6 </u>
y = 4
-2x + 7(4) = 10
-2x + 28 = 10
<u> -28 -28</u>
<u>-2x</u> = <u>-18</u>
-2 -2
x = 9
(x, y) = (9, 4)
Answer:
Step-by-step explanation:
To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.
Answer: B
Step-by-step explanation:
Answer:
5+5+5+5
4+4+4+4
5*4
Step-by-step explanation:
1. You have the following multiplication given in the problem above is:
4*5
Then, the product is:
4*5=20
2. The multiplication indicates that the number 4 is added five times,as following:
4+4+4+4+4=20
3. The multiplication also indicates that the number 5 is added four times,as following:
5+5+5+5=20
4. The commutative property says that you can change the order of the factors but the product does not change:
5*4=20
